although I havent used Matrix Theres a lot of painters around here that love their clear so I would guess their SS paint is just as good...Centari is an acrilic enamel even if you use a hardner it wont last near as long as a urathane ....it is cheaper but urathane is what you really want...
when sprayed right you cant tell SS from BC/CC unless you actually sand it. as long as its a solid color...metalics are a whole nuther story....
